1. Lateral Pterygoid
You need to dissect the mandible in order to see this
Works with medial pterygoid to lower the mandible and open the jaw
This is a deep muscle

2. Rectus Abdominis
Flexes lumbar portion of vertebral column

3. External Obliques
Individual: lateral flexion and rotation of vertebral column
Together: Flexes vertebral column and compresses abdominal wall

4. Internal Obliques
Individual: lateral flexion of vertebral column and rotation of vertebral column to opposite side
Together: Flexes vertebral column and compresses abdominal wall

5. Transversus Abdominus
Individually: lateral flexion of vertebral column
Together: Flexes and compresses vertebral column

6. Medial Pterygoid Origin: Lateral pterygoid plate of sphenoid
Insertion: Ramus of the mandible
Action: Close jaw; lateral excursion

7. Gluteus Medius Origin: Upper lateral portion of ilium
Insertion: Lateral part of the greater trochanter
Action: Abducts and medially rotates the hips

8. Sartorius Origin: Anterior, superior spine of the ilium
Insertion: medial surface of the tibia
Action: Flexes, abducts, and laterally rotates the hip; flexes the knee.

9. Adductors Longus Origin: Pubis Insertion: Linea aspera of femur
Action: Adducts hip; flexes knee

10. Adductor Magnus Origin: Pubis Insertion: Linea aspera of femur
Action: Adducts hip; flexes knee

11. Sternocleidomastoid: if tone side contracts it rotates and tilts the head sideways; if both side contract it draws the head forward and down; flexes neck

12. Gracilis: adducts hip; flexes knee

13. Rectus Femoris: flexes hip (femur); extends knee

14. Vastus medialis: extends knee

15. Vastus lateralis: extends knee

16. Masseter: closes jaw (elevates and retracts mandible)

17. Digastricus: opens the mouth (lowers mandible), elevates and holds hyoid during speech and swallowing

18. Gluteus maximus: extension and lateral rotation of hip (femur)

19. Semimembranosus: extends hip (femur); flexes knee

20. Semitendinosus: extends hip (femur); flexes knee

21. Temporalis
Closes the jaw.
Elevates the mandible.

22. Biceps Femoris Anterior View Posterior View
The muscles has two different origins and one insertion resulting in a branched muscle.
The long head of the muscle originates from the ischial tuberosity and functions to extend and laterally rotate the hip.
The short head of the muscle originates on the linea aspera of the femur.
Both the long and short head insert on the head of the fibula and lateral condyle of the tibia.
Both the long and short heads function to flex the knee.

23. Tibialis Anterior
Dorsiflexion and inversion of the ankle.

24. Gastrocnemius
Plantarflexion of the ankle
Flexes the knee

25. Soleus
Plantarflexion of the ankle.
Steadies the leg when standing.
